Cheaper by the Dozen - Frank B. Gilbreth Jr., Ernestine Gilbreth Carey

What do you get when you put twelve lively kids together with a father -- a famous efficiency expert -- who believes families can run like factories, and a mother who is his partner in everything except discipline? You get a hilarious tale of growing up that has made generations of kids and adults alike laugh along with the Gilbreths in Cheaper by the Dozen.
